Remember bookmarks? It’s how we used to save sites to go back to later. In theory anyway. Browser bookmark search was pretty terrible, and you had to remember the name of the site to find it again. So we mostly just used Google to search for a site every time we wanted to go there.

A new Safari feature hidden within the latest Mac OS X Lion build is expected to compete with services like Instapaper and ReadItLater as a method of saving pages for later reading. The ‘Reading List’ feature appears to be partly based on HTML and javascript, and is likely synchronize bookmarks between Mac and iOS devices.

Discovered by MacRumors, Apple’s description of the feature is the following:

Reading List lets you collect webpages and links for you to read later. To add the current page to your Reading List, click Add Page. You can also Shift-click a link to quickly add it to the list. To hide and show Reading List, click the Reading List icon (eyeglasses) in the bookmarks bar.

The feature is currently inactive within the latest build of Lion, so those running the release won’t be able to try it out just yet, but as a massive Instapaper addict I can’t wait for Reading List to go live.
